How to recognize atopic dermatitis?

What are the symptoms of atopic dermatitis?

While atopic dermatitis does not always manifest in the same way, certain symptoms are very common:

• very intense (even obsessive) itching, often localized in certain areas;

• redness with a sensation of heat or irritation;

• inflammatory lesions that can sometimes become infected;

• ultra-dry skin, even in areas not affected by patches.

How does a doctor diagnose atopic dermatitis?

The diagnosis of atopic dermatitis begins with a visual examination of the skin: the lesions are usually typical, meaning recognizable enough to guide the doctor.

However, to properly understand the origin of the symptoms, the healthcare professional will primarily ask you a number of questions: your family history (eczema, asthma, allergies), possible triggers, the frequency of flare-ups, your lifestyle, etc. This is called anamnesis.

Indeed, atopic dermatitis is a complex disease, influenced by several factors: it is necessary to find the puzzle pieces one by one to understand its causes.

Is there a laboratory test for atopic dermatitis?

Unfortunately, there is not yet an official test to diagnose atopic dermatitis. Everything relies essentially on clinical observation and doctor-patient interaction.

In some cases, the doctor may suggest additional examinations if they suspect a more severe form of the disease or an associated allergy. This is referred to as an allergy workup:

• skin tests to look for reactions to common allergens (dust mites, pollens, foods);

• a blood test to measure specific IgE, antibodies involved in allergic reactions.

What are the different levels of atopic dermatitis?

Mild atopic dermatitis

The patches are few and well-localized, often in the skin folds (elbows, knees). The skin is dry and may itch occasionally, but the symptoms remain tolerable. The discomfort is real, but personal/professional life is minimally disrupted.

Moderate atopic dermatitis

The patches become more visible or more widespread. Itching is much more intense. Scratching significantly impacts sleep, and fatigue begins to set in. At this stage, the disease has a real impact on social, academic, or professional life.

Severe atopic dermatitis

Inflammatory lesions affect large areas of the body; they may ooze or become infected. Itching is difficult to control, sleep is severely disturbed, and fatigue becomes chronic. Increased medical monitoring becomes necessary.

Why is a diagnosis important?

Skin that itches, burns, and wakes you up at night is not trivial: atopic dermatitis can truly ruin daily life: 46% of patients suffer from the impact of this disease on their professional life or studies. And yet, the correct diagnosis is not always made immediately. It's often initially thought to be a temporary allergy, contact eczema, or "just" dry skin...

Putting a name to the disease is already a relief. It allows you to understand what is happening and, above all, to identify the true triggers of flare-ups. This is a first step towards appropriate treatment!
